As I have two 8032-SK's to diagnose, I am flipping a bit between them so forgive me if it gets confusing
Have nothing on the screen of the second unit, I note that I dont have the 400V signal at the brightness controls. Now looking at the circuit diagram for the monitor and checking the loop I found that R252 was open circuit.
Its listed as a 56 ohm RN 1/4 and is of a form I'm not familiar with. It looks like an externally etched metal film, which would be for accuracy and stability ?. Hugo, is there anything special about these resistors ? I note that they have a standoff on one end to lift them from the PCB, Heat or prone to failure ?
I have replaced it temporarily with a 1/4W carbon film and the monitor has now sprung into glorious life but I dont want to leave it like that if I really need to put the right type of resistor in.
